Firefox and CPU fan

[ale]

Each time that I start Firefox, i hear a strong noise form the CPU fan
running at full speed. To be noted that this happens even with the
simple start page, so no flash plugins are operating. CPU is doing
almost nothing, at least looking ant the windows task manager.
No add-ons installed.

I guess it is a problem related to Firefox because when I do heavy
calculations on the same workstation but with different softwares, the
problem does not appear.

Win7-x64 SP1, 8 GB RAM

CPU fans normally work based on the temperature of the CPU, not on what
program is loaded. You might load something like 'coretemp' or other
temperature display software that can monitor your CPU temps. IF the
fan is not responding to the temperature of the CPU, then you might want
to check with your computer manufacturer to see if they have any idea.

I'm not the only one.

disabling hardware acceleration under options-->advanced-->general
solved the problem for me too, as described in the link.

There are several reports of noisy _GPU_ fans caused by hardware
acceleration. Some people report short temperature spikes. It seems that
thermal control on some video cards is poor.

So this might be the GPU. If it's really the CPU fan that would be odd.
Would a board with on-board graphics do this? Would Fx attempt hardware
acceleration on such a system?

(I've never had h/w acceleration working here on Linux - even with some
quite flashy video cards.)

May be you are right, it was the GPU and not the CPU fan (I didn't open
the cabinet), BTW we are speaking of a top-class Nvidia Quadro Fx4000,
and I don't understand why a 3d-cad that makes strong use of OpenGL
libraries and graphic power does not shows the issue, and a "simple"
browser does.

If you're bothered you could install some software that monitors
temperature and fan speed and work out what's happening. There's a
program mentioned here:

firefox

There may be a firmware or driver update.

I am running it & the fan's RPMs don't rev up near as much; also, Ff
uses less RAM.

Does not play well w/ Avast AV, however.

Hardware acceleration should ease CPU usage.
See
<http://support.mozilla.org/en-US/kb/Firefox%20consumes%20a%20lot%20of%20CPU%20resources#w_checking-firefox-hardware-acceleration>.

If it's having the opposite affect, try updating your graphics drivers.

BTW--when I open Iron, the fan really cranks up--talk about a memory
hog!! But Ff is the one that gets badmouthed.....
